LMV7271MF/NOPB

Overview

The LMV7271MF/NOPB is a single-channel analog comparator from Texas Instruments, characterized by rail-to-rail input and push-pull output capabilities. It operates within a supply voltage range of 1.8 V to 5.5 V, consuming as little as 9 µA of supply current per channel. The device features a propagation delay of 800 ns and an input offset voltage of 4 mV. It provides an output current capability of 34 mA per channel with a common-mode rejection ratio of 46 dB and power supply rejection ratio of 55 dB. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Rail-to-rail input stage enables operation with signals extending to the supply rails.
• Push-pull output stage allows for low-power driving of loads without external pull-up resistors.
• Low power consumption design supports battery-operated applications with minimal quiescent current.
• Advanced BiCMOS process ensures improved noise performance through bipolar inputs.

Applications

• Level-shifting applications requiring output pull-up to voltages independent of the supply voltage
• Space-critical designs utilizing compact SC-70 or SOT-23 packages
• Low voltage and low power consumer electronics systems

Procurement Notes

Verify the specific suffix 'MF' against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the NOPB designation confirms lead-free and RoHS compliance status. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.

Selection Notes

Select this component when rail-to-rail input compatibility is required alongside a push-pull output configuration. It is suitable for designs prioritizing low supply current under 10 µA while maintaining moderate speed. Consider the SC-70 or SOT-23 package options if PCB area reduction is a primary constraint for the application layout.

Part Context

This device belongs to the LMV727x family of rail-to-rail input low power comparators. The family includes single (LMV7271), dual (LMV7272), and open-drain output (LMV7275) variants. All members share the same advanced submicron silicon-gate BiCMOS process technology, ensuring consistent electrical characteristics across the series while offering different output stages and channel counts.

Replacement Considerations

The LMV7271MFX/NOPB serves as a direct pin-compatible alternative within the same family, differing primarily in packaging format. Verify that the replacement maintains the required push-pull output stage, as other family members like the LMV7275 utilize open-drain outputs which may necessitate circuit modifications.
